Cheating

Dear Sir,
I purchased a packet of 100g Fennel (????), from Reliance mart. The price tag was shown Rs. 26.00/- but the Reliance people charged me Rs.33.00/- for the same. I feel cheated when i came to home & when i check all the things with their price list.
Now Sir, what can i will do.
i heard about this forum, can i get justice for that cheating or else i need to forget about this cheating, because Reliance is a vrey big company and i can’t afford money even for the Lawyer. please do the needful.
Thanks & Regards
